A strain of Trichoderma and its application in agricultural field

Abstract

The invention relates to a Trichoderma strain and its application in the agricultural field. A strain of Trichoderma, named Trichoderma harzianum, was deposited in the General Microorganism Center of China Committee for the Collection of Microorganisms, with the preservation number CGMCC No.15679 and the preservation date was May 21, 2018. The above-mentioned Trichoderma is used to inhibit the growth of Rhizoctonia solani, Anthracnose and Fusarium. The above-mentioned Trichoderma is used for soil phosphorus solubilization. The above-mentioned Trichoderma is used for preparing microbial fertilizer. A strain of Trichoderma disclosed by the present invention and its application in the agricultural field have the following beneficial effects: 1. Provide a bacterial strain for inhibiting Rhizoctonia solani, anthracnose, and Fusarium, which has a good effect on the above-mentioned plant harmful pathogens 2. The bacterial strain can also be used to prepare microbial seed coating agents, which can play a beneficial role in promoting the growth of plant roots without losing activity.

Description

technical field [0001] The invention belongs to the field of biological engineering, and in particular relates to a Trichoderma strain and its application in the agricultural field. Background technique [0002] Worldwide, plant diseases commonly cause severe losses to agricultural production. The control of plant diseases and insect pests in production is often based on traditional chemical control, which has high requirements for the long-term stability of the chemical agents, and the chemical agents will also cause serious pollution to the environment. After pesticides are applied to crops, once they remain, it will greatly affect the quality of agricultural products and seriously endanger human health. With the strengthening of human awareness of environmental protection, the development of green ecological agriculture has gradually become the mainstream, especially in the use of biological methods instead of traditional chemical methods for the prevention and control o...

Problems solved by technology

[0003] At present, most of the biocontrol strains of plant diseases are fungi and bacteria isolated from the soil and the rhizosphere or body surface of plants. Their sources are relatively single and they are easily affected by the external natural environment.

If the environment changes, it is easy to directly affect its colonization ability, and the effect fluctuates greatly when facing different harmful bacteria. It is difficult to prevent and control most diseases, which seriously limits its application range.
